A long history: For over 5,000 years, apple cider vinegar has been used by natural health practitioners the world over. It's been traced to ancient Egyptian urns and there's record that Julius Caesar's Roman army used apple cider vinegar to stay healthy. On the other side of the globe, for centuries Japanese Samurai warriors drank it for strength and power. ¿ In the United States, apple cider vinegar became extremely popular in the 1950s coinciding with the alternative health boom. Since then its use in liquid and then capsule and tablet form has become widespread.

How it's made: Apple cider vinegar is made by crushing apples that then form a liquid. There are two fermentation processes that ultimately turn the solution into a pale, amber-colored vinegar. While the main ingredient of apple cider vinegar is acetic acid, it also contains trace amounts of naturally occurring vitamins, minerals and amino acids that can benefit overall health.
